Electrocoagulation technology
CELDAR® Process

Innovative methods are continuously required to treat a wide range of wastewater pollutants especially in case of difficult approach. Electrocoagulation CELDAR® method optimised by INTECNA, provides a relatively compact and robust treatment/plant alternative in which special alloy metal anodes initiate electrochemical reactions that provide active metal cations for coagulation and flocculation.

What transfer

INTECNA designed and offers two CELDAR® configurations:

COMPACT PLANT,

where in the same structure there are the electrolytic cell, the flocculator and the filtration system. This plant is suitable for treating flows in a range of 700 – 1000 liters / hour.

SEPARATE SECTION PLANT,

where the electrolytic cell supplied by INTECNA is combined with conventional flocculation and sludge treatment sections. This plant has treatment capacity over 2 cubic meters / hour and is modular since more cells can be installed with maximum flexibility.

The inherent advantage of electrocoagulation is that no coagulants have to be added to the wastewater and hence the salinity of the water does not increase after treatment. That is a winning factor if wastewater re-use is the aim of the users.

During the last 10 years, many waters have been tested in the INTECNA Laboratory with characteristics that are difficult to treat through conventional methods.
In particular, we had good results with the following treatments:

FLEXOGRAPHY WATER for photopolymer removal
DYEING WATER for colour removal
LANDFILL WATER for heavy metals removal
GALVANIC WATER for surfactants removal
WATER FOR SURFACE TREATMENT OF ALUMINUM for fluorides removal
WATER FROM EMULSIONS OF OIL for breaking emulsions
PHOSPHATE WATER for phosphorus removal
PAINT BOOTH WATER: for overspray removal
